Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance with MSL Rating 1 (Unlimited), ensuring regulatory and environmental compatibility across designs.

MCP1525T-I/TT is the primary reference part with 2 mA output current and 50 ppm/°C temperature coefficient, suitable for applications requiring moderate output current within the 2.7V to 5.5V input range.

MAX6002EUR+T provides the lowest supply current (45 µA) and extended input voltage range (2.7V ~ 12.6V), making it suitable for low-power applications or systems with higher input voltage requirements. Output current is limited to 400 µA.

MAX6125EUR+T matches the temperature coefficient of the primary part (50 ppm/°C) and supports extended input voltage range (2.7V ~ 12.6V) with 1 mA output current, offering a balanced alternative when higher input voltage tolerance is required.

Frequently Asked Questions (FAQ)

Q: Can MAX6002EUR+T replace MCP1525T-I/TT in all applications?

A: MAX6002EUR+T is electrically compatible in terms of output voltage, tolerance, and package. However, its 400 µA output current is lower than the MCP1525T-I/TT's 2 mA. Substitution is valid only if the application circuit does not require output current exceeding 400 µA. The extended input voltage range (2.7V ~ 12.6V) is a superset of the original specification.

Q: What is the difference between MAX6002EUR+T and MAX6125EUR+T?

A: Both parts share the same output voltage (2.5V), tolerance (±1%), and extended input voltage range (2.7V ~ 12.6V). MAX6125EUR+T provides 1 mA output current and 50 ppm/°C temperature coefficient, matching the MCP1525T-I/TT more closely. MAX6002EUR+T offers lower supply current (45 µA) but reduced output current (400 µA) and higher temperature coefficient (100 ppm/°C).

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the SOT-23-3 package (TO-236-3, SC-59) with identical pinout, enabling direct PCB substitution without layout modifications.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All three parts operate across -40°C ~ 85°C (TA), ensuring thermal compatibility in equivalent designs.

Q: Which substitute part should be selected for low-power applications?

A: MAX6002EUR+T is recommended for low-power designs due to its 45 µA supply current, the lowest among the three options. Verify that the 400 µA output current specification meets circuit requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. MCP1525T-I/TT, MAX6002EUR+T, and MAX6125EUR+T are all ROHS3 Compliant with MSL Rating 1 (Unlimited), meeting environmental and regulatory standards for equivalent component selection.
